Given: 8co + 17h2 → c8h18 + 8h2o in this chemical reaction, how many grams of h2 will react completely with 6.50 moles of co? express your answer to three significant figures.

Mass of H2  = 27.6 g

Explanation:

Given:

Moles of CO = 6.50

The balanced reaction is:

8CO + 17H2 → C8H18 + 8H2O

Based on the reaction stoichiometry:

8 moles of CO reacts with 17 moles of H2

Therefore, 6.50 moles of CO would react with:

=

Molar mass of H2 = 2 g/mole

Mass of H2 reacted =

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
